Referring to the drawings by reference characters I have shown my invention as embodied in a copy reader which is indicated generally at |30. The copy reader is shown as mounted on a desk door 26 which includes a top 33. As shown the copy reader |30 includes a rectangular frame section |33 includes ahorizontal portion |35 and` a vertical portion |36. -Positioned in the lower end of the vertical section |36 I provide a pivot stud |31 which includes a polygonal lower section l|38 which is removably positioned in a suitable polygonal socket member |39 provided in the type- 5. writer drawer 26. The vertical section |36 adjacent the stud |31 is provided 'with a set screw |40 for securing it to the stud.

The rod section |34 includes a horizontal por-I tion |4| and a vertical portion |42. The hori- 1Q zontal portion |4| of the rod |34 is positioned in the horizontal portion |35 of the tubular section |33 which is provided with a set screw |43 yfor securing the rod to the tubular section.. The Vertical portion |42 of the rod is positioned in a 15, suitable depending bearing member |44 on the frame |3I. The bearing member |44 is provided with Va set screw |45 for adjustably securing the rod to the frame.

Mounted on each side of the frame |3| adjacent the front thereof I provide vertical rail members |41 (see Fig. 2) each of which includes a front V-shaped groove |48 and a rear V- shaped groove |49.

Mounted on the frame |3| I provide a carriage g5 member which is indicated generally at |50.4 AsN shown the carriage |50 includes a face portion |5| having side bracket portions |52 thereon which extend rearwardly to the outside of the rail members |41. Each of the side brackets |52 has 3Q a pairof upper front and rear V-shaped rollers "l |53 and |54 and a pair of lower front and rear` V-shaped rollers |55 rotatably secured thereto. The front rollers |53 and |55 arepositioned in the front V-shaped track groove |48 and the rear rollers |54 and |55 are positioned in the rear V-shaped track groove |49. One of the rail mem. bers |41 in its outer face has a vertical dovetailed groove |51 therein.

Mounted on the carriage bracket |52 adjacent 49 the groove |51 I provide a bolt member |58 the head |59 of which is suitably shaped to slidalolyv t within the adjacent dovetailed groove |51. The opposite end of the bolt |58 has a nut |60 thereon and intermediate the side of the bracket 5 |52 and the nut |60 I provide a pair of opposed spring membersv |6| which engage a washer |62. When the nut |60 is tightened against the action of the spring members |6| the bolt head |50` frictionally engages the beveled wallsof the dove- 50 tailed groove |51. Sufficient friction is provided between the head |59 and the rail' 41 to partlyv overcome the weight of the carriage |50. AThe` face portion |5| of the carriage (see Fig. 6) in- Ffa cludes spaced upper and lower -flanges |63 andl 55" of the bracket.

intermediate the flanges |53 the face portion I5| has a viewing aperture |58 therein.

Positioned between the side brackets |52 and between the anges |53 I provide an elongated magnifying glass member |85. The magnifying glass |55 adjacent each end has an aperture |85' in which an internally threaded sleeve is positioned. The inner end of the sleeve is outwardly flared to form an enlarged flange |58 which engages the rear surface of the glass |85 and the front end of the sleeve has an enlarged head |85 thereon which engages the front surface of the glass |85.

Mounted on the frame |58 adjacent each side thereof I provide threaded rods |81 which are positioned one in each of the sleeve members |68. Thus by rotating the sleeves |85 the magnifying glass |95 may be moved either towards or away from the face portion |53. In each end the magnifying glass member |55 has a polygonal recess |68 therein (see Fig. 2). The glass |85 may be removed and the recesses |58 may receive the ends of arms on a title reading device (not shown).

Positioned below the magnifying glass |85 I provide an electric lamp socket and shade member |89 (see Fig. l) which is mounted on a rod |10 which isI in turn removably positioned in a suitable bearing portion 1| (see 6) on one of the side brackets |52 and has a set screw |12 therein to removably secure the rod |19 to the carriage.

Pivotally mounted in a boss 18| on the copy reader frame |8| I provide a horizontally and vertically adjustable flood lamp |89.

Removably positioned in the frame |88 I pro- Vide a copy holder which is indicated generally at |13 and shown indetail in Fig. 9. As shown the copy holder |13 includes a plate portion |14 having upper and lower rearwardly extending flanges |15. Intermediate its height at each side the plate portion |14 includes rearwardly eX- tending arm portions |18 having outwardly eX- tending finger portions |11 thereon. Suitably secured to each of the arm portions |16 I provide an outwardly curved at spring member |18 which when the copy holder is positioned in the frame ISI as shown in Fig. 2 frictionally engages the sides of the frame. On theframe |8| I mount a spring wire page retention clip |18.

As shown in Fig. lA the central portion of the clip |18 curvesI upwardly and rearwardly behind the front of the frame ISI as indicated at |18 so that the hand oi the operator which raises the sheet of copy may strike and raise the clip to allow the sheet of copy to be positioned therebeneath.

Adjacent to the top and each side the plate portion |18 has an aperture |19 therein in which a clamp member |88 is positioned. (See Fig. 18.) As shown each of the clamp members |88 comprises a at spring curved back upon itself with one end in the rear of the plate |18 and secured to the plate as by rivets 18| and the other end engaging the front of the plate |14.

Secured to one of the brackets |52 of the carriage and vadjacent to the rear thereof I provide a depending gear toothed rack member |83 (see Figs 4 and 5). Mounted on the frame 18| cn the side adjacent the rack |83 I provide a bracket member |84. Rotatably mounted on the bracket |88 I provide a shaft |85 having a gear |88 mounted thereon at one side of the bracket and a ratchet wheel |81 thereon to the opposite side The gear |86 meshes with the rack |83 and the ratchet wheel |81 is adapted to be intermittently engaged by a pawl |88.

Coaxial with the shaft |85 and inward from the gear |88 I provide a threaded stud |88' which is suitably mounted on the frame I3 I. Positioned on the threaded stud |86' I provide an internally threaded sleeve I86a which has an enlarged liber head member |8517 thereon. The exterior of the sleeve |86a is axially knurled and is engaged by a spring member |860 which is mounted on a portion of the frame ISI. The liber head |882; is adapted to frictionally engage the face of the gear |88. Sufcient friction is provided between the fiber head |88b and the gear |88 to partly overcome the weight of the carriage |50. Thus the friction means |59 and the friction means |851) overcome the entire weight of the carriage |50. The pawl |88 is pivotally mounted as at |89 on a slide member |99 and includes a rearwardly extending arm portion |9|.

For resiliently retaining the pawl |88 out of engagement with the ratchet |81 I provide a lat spring member |92 which isf anchored at one end to the slide as at |98 and with the opposite end engaging the pawl arm |9|. 'Ihe slide |99 has elongated slots |94 therein i-n which screw members |95 secured to the bracket |84 are positioned.

To limit the upward movement of the slide |90 I provide a stop member |98 which is adapted to be engaged by a nger |91 on the slide. As shown in Fig. 8 the stop |96 has a screw |99 secured thereto which is positioned in an elongated slot |99 in the bracket |84 and has a washer 285 thereon which is urged by spring 28| into frictional engagement with the bracket |89. The slot |99 in one side thereof has a plurality of V- shaped notches 282 in one of which a similarly shaped portion 283 of the stop |95 is adapted to be positioned. To shift the stop member |99 the screw |98 is pushed against the tension of the spring 20|. This allows the member |96 to move away from the bracket |84 so that the portion 283 of the stop is moved from. the notch 202. The member |98 is then shifted as desired and released so that the portion 203 enters the selected notch 282.

For resiliently urging the slide |90 downwardly I provide a coiled spring 204 surrounding a rod 285 which is mounted on an out turned lip 288 on the slide and is slidably positioned in a suitable aperture in an out turned lip 201 on the bracket |84.

Mounted in a bearing portion 288 integral with the bracket I 84 and below the pawl arm |9| I provide a plunger rod 289 which is square in cross section as shown in Fig. 4A. Extending outwardly from three sides oi the plunger rod above the bearing 208 the plunger includes equally spaced operating nger portions 209' which are adapted to engage the arm |9| of the pawl |88. The plunger has one face with no finger portions thereon to provide a neutral side which causes no movement of the carriage when this neutral side is adjacent to the pawl arm, |9|.

The bearing 288 includes a reduced threaded portion 2|0 having a reduced aperture 2| therein. Positioned in the aperture 2|| I provide a ilexible push rod 2|2 which is mounted in a flexible conduit member 2 I8. At one end the conduit 2|3 includes' an internally threaded coupling member 2M which is adapted to engage the reduced threaded portion 2| 0 of the bearing 208.

At the opposite end the conduit 2|@ includes a similar internally threaded coupling member 2I5 which is adapted to engage a reduced threaded portion 2 I5 of a vertical bearing member 2|6 which is supported on an arm 2|l which is on a base 2|8.

The vertical bearing member 2|5 has an aperture 2 I 9 therein and a reduced aperture 220. Positioned in the aperture 2|9 I provide a spring pressed plunger 22| which includes a reduced poru tion 222 which is positioned in the reduced aperture 220. Furthermore the lower end of the flexible push rod 2|2 is positioned in the apern ture 220 and is adapted to be engaged by the reduced portion 222. The lower end of the plunger 22| has a roller member 223 rotatable thereon which is adapted to engage a portion 22d of foot or hand lever 225 which is pivotally mounted as at 226 intermediate its length on a bracket 227 on the base 2|8.

When the foot or hand lever 225 is swung downward the portion 224 thereof moves upward and forces the plunger portions 22| and 222 upward therewith thus moving the exible push rod 2|2 upward which in turn moves the plunger 209 upward. As the plunger 209 moves upward the uppermost of the iingers 209 thereon swings the pawl arm |9| upward against the action of the spring |92 thereby moving the pawl |88 into engagement with the ratchet wheel |81. Continued upward movement of the plunger 209 moves the slide member |90 and the pawl |88 upward and as the pawl moves upward it rotates the ratchet |81. When the ratchet |21 is thus rotated it rotates the shaft |85 which in turn rotates the gear |89 and as the gear |80 rotates it moves the rack member |03 and the carriage |50 downwardly a predetermined distance. The stop member |96 may be set to stop the slide |90 at various positions to thereby limit the downward movement of the carriage |50.

In Fig. 11 I have shown the flexible push rod 2|2 as adapted to be actuated from the platen rotating means of a typewriter which is indicated generally at 230. The typewriter 230 includes a platen rotating ratchet wheel 23| which is adapted to be engaged bya dog member 232 mounted on an arm 233. As shown in Fig. 11 I provide a bearing member 234 which is adapted to be suitably secured to a portion of the typewriter carriage by screws 235. The bearing 234 has an aperture 236 therein and a `reduced aperture 231. The bearing 234 includes a reduced threaded portion 238 to which the coupling member 2|5 of the conduit 2|3 is adapted to be secured. Positioned in the aperture 236 I pro-` vide a plunger member 239 which includes `a reduced portion 240 which is positioned in the reduced aperture 23'! and engages the end of the flexible push rod 2|2.

The opposite end o the plunger 239 has a link 24|v pivotally secured thereto as at 242 and the opposite end of the link 24| is pivotally connected as at 243 to the typewriter arm 233. Thus when the operator of the typewriter 230 actuates the correct mechanism to rotate the platen the arm 233 moves the bearing 243 thereby pushing the link 24|, the plunger 239 and reduced portion 240 toward the conduit 2|3 thereby moving the exible push rod 2|2.

When the push rod 2|2 is operated by the platen rotating means or a typewriter as shown in Fig. ll the stop member |96 is moved to its uppermost or number 3 position and the amount of movement of the ratchet* IB'I is controlled by correctly positioning the iingers 209' on the plunger rod 209. That is when three spaces are desired the operator sets the rod 209 so that the uppermost nnger 209' will engage the pawl arm |9I, when only two spaces are required the operator sets the rod 209 so that the uppermost finger 209 is out of the path or the pawl arm and the intermediate iinger 209 will engage the pawl arm and when only one space is required the operator sets the rod 209 so that only the lowermost nger 209 is in the path of the pawl arm. To change the spacing the rod 209 is removed and rotated. In order to do this the stop 1 member |99` is iirst moved to its upper position in the manner previously described. When in this position the slide member |99 is raisedto its upper limit. This raises the pall |33 and the arm |9| thereon so that lthe arm is raised sufiiciently to allow the rod 229 to be turned to the correct position whereupon the rod is reinserted and the other partsv brought to normal operative position. Furthermore the operator may set the rod 209 so that all the iingers y209 i are out of the path of the pawl arm whereupon when the typewriter platen is rotated none of the fingers 209 will engage the pawl arm and thus the ratchet |81 will not be rotated.
